New version of program STeelCON 2015.015
January 2015 http://www.sofistik.gr/ Steel Structures New version of program STeelCON 2015.015 Dear colleagues, A new version of the “STeel CONnections” program for the design of bolted and welded steel connections has been released. This new version offers many new features : o New connections between tubes. X type connections uniplanar or multiplanar.

The validity range evaluation ensures that the failure modes of the connection will be the same with the expected ones by the rule. For connections that belong into the validity range some failure types can be neglected under certain conditions, but for connections outside that range some failure modes that are not documented in the rule and need separate handling may happen. The program performs all the necessary geometrical checks and informs the user in the case that the node is out of the range of validity. Furthermore the user has the option to add appropriate stiffener plates at the flanges or the web of the chord in order to reinforce the strength of the connection. The program will calculate the minimum dimensions and weld thicknesses. The members can have axial force, tension or compression, and in plane and out of plane moments, according to the connection type. The program calculates the interaction of these forces according to EN 1993-1-8. o New Cross Sections are added to the library: Canadian Cross Sections: CISC_L CISC_HSS CISC_HSS_Round CISC_Chann CISC_Wide_Flange Japanese Cross Sections JAP_H_JIS_G_3192 Chinese Cross Sections Chinese_L Chinese_I_H Chinese_Chann SOFiSTiK HELLAS A.E. 3ης Σεπτεμβρίου 56, Τ.Κ. 10433 Αθήνα, Τηλ.: 210 8220607 Fax: 210 8251632, E-mail: [email protected], Web: www.sofistik.gr Of course the user can edit or change the existing cross sections and add new ones. This is done by using our Serial Files Manager (Ser.Man.), which is also improved to match the standards of the new STeelCON Version. o New options for the end plate connections For the end plate connections some new options for the calculation of the slip resistance and the bending strength in the weak axis have been added. The user can decide to consider that the tension force in one side of the connection is counterbalanced by equal compression on the other, so the additional friction on the compressed side ensures the slip resistance of the connection without any reduction, as described at 3.9.2(2) of EN 1993-1-8. This approach is followed widely in the literature and leads to larger slip resistances compared to those calculated using the conservative reduction of 3.9.2(1) of EN 1993-1-8. All the connections between tubes are updated to the provisions of ΕΝ1993-1-8/ΑC2009. SteelCON is SOFiSTiK Version 27 (2012) as well as Version 30 (2014) compatible and can be operated within the SSD integrated SOFiSTiK environment. All geometrical and topological data as well as forces can be imported from the overall structure. Connection design results are then a part of the SOFiSTiK Output Report.
